| 摘 要： | 提出了一种同时支持诸多频带工作的共面波导馈电平面开式套筒天线.共面波导中心金属导带以及接地板均采用渐变的形状,天线采用开式套筒结构,并加入了一个倒L型寄生贴片,以最大程度地展宽天线带宽.与以往所提出的共面波导馈电天线相比,此天线具有尺寸小,覆盖更宽的频带,可同时支持个人通信系统(PCS),宽带码分多址系统(WCDMA)...

| Abstract: | A coplanar waveguide(CPW)fed sleeve antenna which supports multiband applications is proposed.The central feeder line and the ground plane of the CPW are designed to be gradually changed in structure.Open sleeve structure and an inverted-L strip are adopted in the proposed antenna which broader the bandwidth to a great extent.Compared with antennas in previous researches,this antenna has a small size of 56 mm×36 mm×0.8 mm,while covers wider bandwidth,which can support personal communication system(PCS)1900,wideband code division multiple access(WCDMA),universal mobile telecommunicatim system(UMTS),wireless broadband(WiBro),wireless local area ntework(WLAN),worldwide interoperability of microwave access(WiMAX) system at the same time.The miniaturization,broadband and multiband characteristics of this proposed antenna is realized.Antenna shows omni-directivity in azimuth plane.The measured results agree well with the simulated ones,which displays good radiation characteristic and practicability for wireless communications. |
